I need a tutorial or lesson on Xpath syntax from the ground up.  I am totally confused on how to assemble an Xpath.  All the //a[wizardmojo]::stuffgoeshere is confusing as hell, and all the information I find, only tells you very basic examples, they don't really teach you assuming you know nothing.

Thanks in advance, Mike

I'm confused -- don't you *want* very basic examples?

Try http://www.w3schools.com/xpath/xpath_intro.asp

Yes, those examples are good, for about 5 minutes, but then how I do learn to do the more advanced stuff?  Like find all the "a" tags and then extract the "href" out of each one?  Or look in each "tr" and extract all the "hrefs" in "td 1" when "td 4" contains the text "5 star rating"  I haven't found anything that teaches you to string together complex xpaths, just simple ones like //form[1]/input

"XPath" is a public standard. You can find its specification
at "http://www.w3.org/TR/xpath/". In my view, it is very well written;
you find there all relevant details. Of course, it is not a tutorial:
the information is very concise and assumes, that the reader copes
well with abstract descriptions.
